GDXray Castings dataset [1]} contains 2727 X-ray images mainly from automotive aluminium parts, although around 2420 images are properly labelled with BBox defining the exact position of the defect. Most of the images were taken by BAM Federal Institute for Materials Research and Testing (Berlin, Germany). The original 12 bit images were scanned using a LASER scanner LS85 SDR with a pixel size of 40.3 micros (630 dpi) and were transformed to 8 bits using a linear Look-up-Table (LUT) proportional to the optical film density. All images where converted into JPG RGB format with varying sizes: 350x151, 768x572, etc.
